fix(dashboard): exclude dashboard-mode from global font-lock

The dashboard banner title and section headings render in the default face instead of their theme colors. The faces are defined correctly. Global font-lock fontifies the dashboard buffer and strips the `face' text properties dashboard sets by hand: it owns `face' and clears props it didn't apply. Items and the navigator survive because their color rides a dashboard-items-face overlay, which font-lock leaves alone.

Excluding dashboard-mode from global font-lock keeps the banner and heading faces. I set it at top level so it applies regardless of the use-package body.

+;;; Commentary:
+;; `global-font-lock-mode' fontifies the *dashboard* buffer and strips the
+;; manually-applied `face' text properties dashboard puts on the banner title
+;; (`dashboard-banner-logo-title') and the section headings
+;; (`dashboard-heading'), so they render in the default face instead of the
+;; theme colors.  dashboard-config excludes dashboard-mode from global
+;; font-lock so those text-property faces survive.
